The `app` fixture called create_app('testing') for every one of 3173 tests,
registering 90+ blueprints each time. Measured on a fixed 199-test sample
(pytest --splits 16 --group 5 --durations=0):
setup 144.9s 89.5%
call 8.8s 5.4%
teardown 8.2s 5.0%
95% of the suite's time was preparing to test; 5% was testing. The app is now
built once per process and shared.
Same 794-test slice, before and after — identical results, 2.66x faster:
before 4 failed, 773 passed, 17 skipped 593.30s
after 4 failed, 773 passed, 17 skipped 223.11s
(the 4 are pre-existing locally: serverkit-wordpress isn't checked out here.)
Sharing one app surfaces three things a per-test app hid, all handled in the
fixture rather than patched test by test:
1. create_app() is not a pure constructor — it SEEDS the bundled flagship
extension rows as a boot side effect (test_cloudflare_extraction asserts
they are "seeded on boot"). The per-test drop_all wipes them, and a shared
app never re-boots, so every test after the first saw no flagship and the
extension routes answered 503. seed_flagship_extensions() is now re-run
after each create_all. The session fixture also boots twice on purpose:
once to create the schema, once to seed into a schema that exists.
2. Config mutation now leaks where it used to die with the app (e.g.
test_demo_deploys sets DEMO_DEPLOYS_ENABLED=False and never restores it),
so config is snapshotted and restored around every test.
3. Structure mutation cannot be undone at all — Flask has no
unregister_blueprint, and refuses setup methods once an app has served a
request. Those tests opt out via `pytestmark = pytest.mark.fresh_app` and
get a private app. Three groups needed it: 13 modules calling
register_blueprint/add_url_rule directly, 11 that install plugins (
plugin_service hot-loads their blueprints onto the live app), and
test_audit_log which adds routes with @app.route.
Tests using the `wp_extension` fixture are detected from the fixture graph
instead of being marked, since that fixture mounts blueprints on whatever app
it is handed — miss one marker and the failure lands in an unrelated test much
later in the run.
Plan 64 Phase 1. Phase 2 (savepoint rollback instead of create_all/drop_all)
is NOT included: it currently takes the slice from 4 failures to 100 failures
and 201 errors, and needs its own round.

Plan 47 Phase 2. The tunnels blueprint + broker/publish/netutil services move
into builtin-extensions/serverkit-remote-access/backend/ (entry_point tunnels:
tunnels_bp, url_prefix unchanged). Core no longer registers /api/v1/tunnels or
imports the services; the Tunnel/ExposedService models stay core (G2).
New reusable core->extension seam get_installed_extension_attr(slug, module,
attr): the agent gateway reaches TunnelBrokerService.schedule_reconcile through
it, so tunnel self-heal still fires when the extension is installed and no-ops
cleanly otherwise. Backend re-acquisition on upgrade is covered by the Phase-2
migration.
Tests: test_tunnel_netutil.py + test_tunnel_reconcile.py re-homed into
test_remote_access_extraction.py (17), which installs the extension and runs the
helpers/reconcile against its modules.
